Ron, if you have an amplifier in line, check the amplifier relay contacts.
I had to clean the relay contacts in my AL-80B about once per year.
The symptoms were just as you described.

K3 started to exhibit intermittent loss
of gain after a transmission. Sometimes, stomping on the foot switch
brings it back up. Sometimes it takes a short transmission. No real
pattern to when it occurs. Receiver isn't totally deaf. Just way down.
